Question

Based on your slinky experiment

(1) what happened when the transverse waves reached your partners end? Did the reflected wave stay on the same side as you sent it? Draw a diagram showing the incoming and reflected waves.

(2) did the waves go any faster or slower when you tried a variety of amplitudes? Explain how this agrees or disagrees with the equation for a transverse waves velocity.

(3) what did you notice about the speed of the longitudinal waves compared to the transverse waves?

(4) explain what happened when you and your partner both sent waves on the same side. What kind of interference took place?

(5) what happened when waves on opposite sides passed each other?

(6) how did shortening the length of the spring affect the resonant frequencies? How does this confirm the relationship v= alpha f when velocity is constant? (Hint a shorter spring length means smaller wavelengths for each standing wave)

(7) using this knowledge explain how musical instruments create higher and lower tones. Use a string instrument as an example.

Explanation / Answer

they get inversed.

2 ) the velocity did not changed with amplitude

3) they are faster than transverse waves

4) the resultant was sum of both waves and it was greater than both the waves ( constructive interferance)

5) destructive interferance. the waves cancelled each other

6) velocity = wavelength * frequency. shorter spring length means smaller wavelengths for each standing wave. hence higer frequency was observed.

7) guitar has strings. the length of string is varied by creating nodes at two ends. and in this way the frequency is varied.
